Energy: Review
... According to the law of conservation of energy, energy cannot be created or destroyed (it can only be transformed from one form to another). Friction converts mechanical energy into thermal energy. Fission and fusion are nuclear reactions that convert a small amount of mass in a nucleus to an ...
